If you had a version of font that you wanted and legally could use, you can do (since iOS version 3.2):

Add the font file to the project in Xcode (in Resources for example).
Add the key UIAppFonts to the info.plist file and make it an array type.
Add the font file name to the array.
Use it by doing, for example, [UIFont fontWithName:@"fontnamr" size:20].
